i notice that most, but not all, are solarized. Sometimes i get pictures from my brother that come through that way. They look fine everywhere except on the i pad. When I chased it down with him, the software he uses (sometimes) to move his pictures from his camera to his computer is an offbeat system, and I think it uses a particular kind of encoding that the pad does not support. I do not think there is anything easy that you can do about it, short of writing to the site people, and have them get a new camera.....if you really need to see the pictures on your pad, capture them on your pc, resave them in a standard format then sync or e mail them to your self.
This will also happen from time to time with non standard pdf encoders.
